We have always used 4WD vehicles to pull our FW, and boats. Never had to use 4WD to pull the FW but have used it in the snow and ice around here. Another reason for our 4WD is to put our boat into and pull it out of the lakes we fish in. If you get on a slippery ramp, or drop your rear reals off the end, 4WD is a Godsend. We once pulled a guy up the ramp at Jackson Lake late in the year after he launched a boat and dropped his rear wheels off the ramp, very low water, and didn't have 4WD. Just unhitched my GMC 4WD, hooked up to his Ford, and pulled him out quite easily, using 4WD. If my wife would have taken pictures of the GMC pulling the Ford out of the lake, GM might have given me a bunch of money for them, but she was too busy talking to the boat driver to do that. Oh well, our loss, but memories stay with us.
